Volume Formulas
| Shape | Formula | Example |
|---|---|---|
| 📦 Cube | side³ | side 5cm = 125cm³ |
| 📐 Rectangular Prism | length × width × height | 10×5×4 = 200cm³ |
| 🥫 Cylinder | π × r² × h | r=5cm, h=10cm = 785cm³ |
| ⚽ Sphere | 4/3 × π × r³ | r=6cm = 904cm³ |
| 🍦 Cone | 1/3 × π × r² × h | r=4cm, h=9cm = 151cm³ |
| 🔺 Pyramid | 1/3 × Base Area × h | base 6×6, h=10 = 120cm³ |
| 🔻 Triangular Prism | 1/2 × b × h × L | b=6, h=4, L=10 = 120cm³ |
* π (pi) ≈ 3.14159. All measurements should be in the same unit (e.g., all in cm, all in inches).

Volume Comparison Guide
Cube (side 5cm)
125 cm³
Smallest volume
Sphere (r=5cm)
523.6 cm³
4.2× cube volume
Cylinder (r=5cm, h=10cm)
785.4 cm³
6.3× cube volume
Different shapes with same dimensions can have vastly different volumes. The cylinder holds the most volume among these examples.
Volume Calculation Tips
- 💡Use consistent units: All measurements must be in the same unit (e.g., all cm, all inches). Mixing units will give incorrect results.
- 💡Remember π (pi): π ≈ 3.14159. For quick estimates, 3.14 is usually sufficient. For exact calculations, use the π button on your calculator.
- 💡Volume increases exponentially: Doubling the side length of a cube increases volume by 8 times. Doubling the radius of a sphere increases volume by 8 times.
- 💡Use the right formula: Each shape has a specific formula. Using the wrong formula is the most common mistake. Our calculator selects the correct formula automatically.
- 💡Check your answer: Volume should be in cubic units. If you get a result in square units, you've used the wrong formula. Our calculator shows both the formula and result.
